Automatic machine for dispensing an ice-cream portion

Abstract: An automatic machine for dispensing an ice-cream portion comprises, in combination, a dispenser (10) for dispensing cones (18) or the like in an inverted position, and a seat (20) arranged to receive said cone (18) in an upright position and to convey it to an ice-cream delivery mouth (27). Between said cone dispenser (10) and said seat (20) there is provided a cone (18) overturning and feed device (12) arranged to receive a cone (18) in an inverted position, to overturn it into an upright position and to feed it automatically into said seat (20).

Description: This invention relates to a completely automatic machine of the coin or token type for dispensing an ice-cream portion, with which a dispenser for dispensing cones or like containers to contain the product is associated. A semi-automatic coin or token machine for dispensing an ice-cream portion is described for example in EP-330252. A cone dispenser which can be associated with said machine is described for example in EP-A-379238. For a complete understanding of the present invention, the description and drawings of EP-330252 and EP-A-379238 are to be considered as forming part of the present patent application, but are not reproduced for simplicity of description. As is well known to the expert of the art, coin or token operated machines for dispensing an ice-cream portion (so-called soft machines) are known in which the customer manually withdraws the cone from a dispenser associated with the machine and places it in a seat in the machine, which then conveys the cone to an ice-cream delivery mouth. After filling, the cone is presented to the customer who removes it. Machines of this type have the drawback that the fact that the customer has to handle the cone is not only inconvenient but can also lead to mistakes in carrying out the required sequence of operations as the manner of using the machine may not be immediately obvious to the customer, and is also questionable from a hygienic viewpoint. The object of the invention is to obviate the drawbacks of the known art by providing a machine for dispensing an ice-cream portion associated with a cone dispenser, in which the entire cycle occurs automatically without any manual action by the customer except for inserting the coin or token and withdrawing the cone containing ice-cream. Said object is attained by a machine having the characteristics defined in the accompanying claims. The structural and functional characteristics of the invention and its advantages over the known art will be more apparent from an examination of the following description, given with reference to the accompanying drawings which show one embodiment of a machine incorporating the principles of the invention. In the drawings: Figure 1 is a vertical section showing the automatic device for feeding a cone to the ice-cream machine; Figures 2a and 2b together show the ice-cream machine in its various operating stages. In the drawings, the reference numeral 10 indicates overall a dispenser for cones or the like, which is preferably but not necessarily of the type described and illustrated in EP-A-379238, and 11 indicates the dispensing station of an ice-cream machine, which is preferably but not necessarily of the type described and illustrated in EP-330252. The reference numeral 12 indicates overall a cone overturning and feeding device, which is positioned between the cone dispenser 10 and said ice-cream dispensing station 11. The device 12 of the invention is formed structurally from a tubular container 13 closed at the end 14 and open at the opposite end. Said tubular container 13 is pivoted at 15 in a manner rotatable between a vertical position indicated in Figure 1 by full lines, and an oblique position indicated in Figure 1 by dashed lines. The tubular container 13 is rotated by a suitable means, such as a geared motor indicated schematically by 16. The reference numeral 17 indicates a photoelectric cell able to detect the presence of a cone 18 within the container 13. Downstream of the tubular container 13 there is provided a chute 19, also tubular, which is aligned with the container 13 when this is in the dashed-line oblique position. The chute 19 enables a cone 18 to fall by gravity into an annular seat 20 in the station 11. Said annular seat 20 is rigid with a carriage 21 driven by a geared motor 22 into the three positions indicated in Figures 2a and 2b by full lines, dashed lines and dashed and dotted lines respectively. The reference numeral 23 indicates a photoelectric cell able to detect the presence of a cone 18 in the seat 20, 24 indicates a limit microswitch for the lower position of the seat 20, 25 indicates a limit microswitch for the upper position of the seat 20, and 26 indicates a microswitch determining the intermediate position of the seat 20, as described hereinafter. The reference numeral 27 schematically indicates an ice-cream delivery mouth or delivery head able to automatically deliver an ice-cream portion into the cone 18 when in its upper position (shown by dashed lines in Figure 2b) within the station 11, which is protected by a transparent door 28 opened and closed by vertical sliding under the control of a geared motor 29 via a linkage comprising a pinion 30 and rack 31. The reference numerals 32 and 33 indicate two sensors for sensing when the door 28 is in its open and closed position respectively, and 34 indicates a photoelectric cell for sensing when the cone containing ice-cream is in the intermediate withdrawal position indicated by dashed and dotted lines. The operation of the machine according to the invention is clear from the aforegoing description with reference to the figures, and is briefly as follows. A cone 18, in the inverted position, is discharged by gravity in known manner by the cone dispenser 10 into the tubular container 13, which is in the vertical position indicated by full lines in Figure 1. The photoelectric cell 17 detects the presence of the cone in the container 13 and operates the geared motor 16, which rotates the container 13 into the dashed-line oblique position aligned with the tubular chute 19, and determined by a microswitch 35. With the tubular container 13 in this oblique position the cone 18 has been overturned, and is discharged by gravity into the chute 19 which conveys it into the ring 20 in an upright position, as shown in Figure 2a. When in this position the photoelectric cell 23 detects the presence of the cone and operates the geared motor 22 which moves the cone into the upright position indicated by dashed lines in Figure 2b, at which it lies in correspondence with the ice-cream delivery mouth 27. This position is determined by the limit microswitch 25. The required portion of ice-cream is delivered through the mouth 27, after which the geared motor 22 is operated to move the cone 20 into the intermediate position, indicated by dashed and dotted lines in Figure 2b and determined by the microswitch 26. With the cone 18 in this position the geared motor 29 is operated to raise the protection door 28, its open position being determined by the sensor 32. The customer can then comfortably remove the cone containing ice-cream by withdrawing it from the annular seat 20. The photoelectric cell 34 senses the customer's action, so that the protection door 28 descends until it closes in a position determined by the photoelectric cell 33. The geared motor 22 returns the annular seat 20 to its lower position shown in Figure 2b, determined by the limit microswitch 24, and the geared motor 16 repositions the tubular container 13 in the vertical position aligned with the discharge mouth of the cone dispenser 10, through which the next cone 18 will be released. The operating cycle involved in dispensing a portion of ice-cream is hence completed fully automatically, and the system is ready for the next cycle. The operating cycle is controlled by a microprocessor associated with an electronic circuit, which is not shown here in detail as it is within the capacity of an expert of the art. The object stated in the introduction to the description is hence achieved, ie of providing a machine able to operate completely automatically, the customer being required only to insert the coin or token, and to remove the cone containing ice-cream.
